Architectural Technologist Dayle Wheeler qualified as Certified Passivhaus Designer

We’re delighted to share that Chartered Architectural Technologist Dayle Wheeler has successfully qualified as a Certified Passivhaus Designer, after undertaking a 2-month course provided by Coaction Training CIC.

The Passivhaus Certified Designer course teaches the core concepts behind the Passivhaus standard, considerations and methodologies for its implementation, and the use of the Passivhaus Planning Package (PHPP) for achieving low energy performance.

Acting as a Technical Lead on many of LSI’s ongoing projects, Dayle is already a qualified PAS 2035 Retrofit Coordinator, and this latest achievement demonstrates his continued commitment to sustainable design and his dedication to delivering high-performance buildings for our clients.

He holds considerable knowledge of regulatory requirements, building fabric and material performance, whole-building retrofit processes, technical detailing, system specification, and designing for accessibility.

Dayle’s recent project experience includes the £13M transformation at Morley College London’s North Kensington Centre for Skills, which provided state-of-the-art new educational facilities alongside modern and inclusive new community facilities. The project incorporated the refurbishment and extension to the existing 1950’s main school building, as well as the demolition of an old caretaker’s building to provide a new garden and landscaping. 


Dayle commented: “I have been interested in the Passivhaus design methodology for many years so it’s really exciting to now be a Certified Passive House Designer.

The science-based approach to designing energy efficient, comfortable and affordable buildings has always appealed to me, particularly the focus on high performance fabric first design principles alongside a high quality of detailing and construction. It’s so important that we as an industry close the performance gap between design and as-built and the Passivhaus methodology has been proven to close this gap.

I look forward to sharing this learning with the wider studio and to applying this learning as we continue to advance the sustainability of our projects.”

Director Mirja Mainwaring added: “Our approach to sustainability in relation to the way we design our buildings always begins at first principles, which we believe is well aligned to the principles of Passivhaus. In our experience this is an effective way of engaging clients and project sponsors in the importance of a considered approach to sustainable design.

We are delighted to see Dayle successfully qualify as a certified Passivhaus designer, which is further recognition of the considerable expertise within our design team.

We are committed to continuing to support our clients in responding to the targets relating to sustainability and net zero, by creating excellent buildings and spaces that are good for both people and the planet.”
